Thread Crash issue while using sendDTMFTones

[Vaibhav.sood15]

Hi my application uses native symbian method to send DTMF tones when call gets connected but whenever the call gets connected it sends 1 DTMF tone and the app rashes saying



Thread has crashed: Thread 0x327 has panicked. Category: Telephony; Reason: 0
Thread has crashed: Thread 0x328 has panicked. Category: Telephony; Reason: 0
Thread has crashed: Thread 0x329 has panicked. Category: Telephony; Reason: 0

is there any permission im missing in the pro file to send DTMF Tones

Any help is much appreciated

Thanks in advance

Also im using a signal when the call gets connected and then using

iTelephony->sendDTMFTones(iStatus, telnumber);

you may see the dial pad example in Qt to see how im using the native API's in qt
